Did David Cameron, then a Special Adviser to Home Secretary Michael Howard, play any part in 1995 in the suppression of child abuse allegations relating to Greville Janner?

It seems to me that some Member of Parliament should raise this matter with Mr. Cameron possibly at Prime Minister's Questions.

Could Mr. Cameron's discomfort about his past actions while at the Home Office go at least some way to explain his disreputable suggestion that the existence of a VIP padeophile ring was attributable to "conspiracy theorists"?
